The Jacumba Wilderness sat largely protected along the U.S.-Mexico border in southwestern Imperial County as recently as last spring. Ocotillos provided pops of bright green that spiraled up from the desert floor, while a field of rare crucifixion thorns sprouted orange berries. Threatened peninsular desert bighorn sheep roamed the nearby ridgelines, mating with a herd south of the fence-less international border.
That all changed when construction began on a new stretch of border wall, made possible by funds pulled from the Department of Defense and by a 2005 act that allowed the government to waive laws to facilitate the wall's construction.
